Writing in the Clinical Journal of Sport Medicine, the specialists said that "aggressive drinking to prevent dehydration is unnecessary and carries with it greater risk."
飲水過量的危害是嚴重的，範圍為頭暈，神誌不清或惡心腦水腫，使大腦膨脹，由於多餘的水分。至少有14名運動員 - 包括一個女人誰完成了海軍陸戰隊馬拉鬆賽於2002年後兩天死了 - 被認為已經從運動中被稱為運動性低鈉血症或EAH條件時飲水過多死亡。
當過量液體積聚在體內鈉的濃度急劇下降和腎髒將會超負荷，無法排泄的水負荷。細胞開始吸收水分。這可能會導致腫脹遍全身 - 最嚴重的大腦 - 這可能會導致癲癇發作，昏迷甚至死亡。
The dangers of overdrinking can be serious and range from lightheadedness, confusion or nausea to cerebral edema in which the brain swells due to excess water. At least 14 athletes — including a woman who died two days after completing the Marine Corps Marathon in 2002 — are believed to have died from drinking too much during exercise in a condition known as exercise-associated hyponatremia or EAH.
When excess fluids build up up in the body the concentration of sodium can drop precipitously and the kidney become overloaded and are unable to excrete the water load. Cells begin to absorb the water. This can lead to swelling all over the body — most seriously in the brain — which can lead to seizures, coma or even death.
